wholesale statement jewelry usa Compared with the pipe gas, the bottle gas is safer, which is safer

wholesale designer jewelry china Pipe gas is safer. Safety factors are mainly compared from three aspects:

⑴ The smaller the pressure, the safer.
The pressure after transporting the pipeline gas is 1500-3000Pa, while the working pressure of liquefied petroleum gas cylinders is generally 800000Pa, which is about 300 times the pressure of the indoor pipeline.
: The smaller the reserves, the safer.
The pipeline pipelines are generally only 3-5 meters, and pipeline gas reserves are only 0.0025 meters 3. The residential bottled liquefied petroleum gas single bottle reserves exceed 10 kg, which is equivalent to about 4 cubic meters of liquefied gas, and the storage volume is more than 1600 times that of pipeline gas.
-易 The easier it is to control the safer.
The bottled liquefied petroleum gas pressure and large reserves, difficulty in controlling during accidents, and easily causing catastrophic consequences. Due to low pressure, small reserves, and multiple valve control in the household gas pipeline, as long as the relevant valve is turned off in time when accidents occur, the accident can be avoided.

The source of gas can usually be divided into natural gas, artificial gas, liquefied petroleum gas and biological gas.
The gas supply industry and developed countries are relatively late. The distribution of gas mainly includes three types: gas, liquefied petroleum gas and natural gas. my country's gas supply has increased significantly since the 1990s.
Among them, after the significant growth of artificial gas supply after 1990, due to its large pollution and strong toxicity, it is in a relatively slow growth stage; liquefied petroleum gas is affected by the rise in oil prices, and the supply has remained maintained. Stablize.
The price of natural gas with the same thermal value is relatively cheaper than gasoline and diesel. It is cheaper 30%-50%, which has obvious economy. At the same time, the country attaches importance to environmental protection. , Cheap energy, natural gas consumption has developed rapidly.
If according to statistics, domestic natural gas imports (including liquefied natural gas) in 2012 (including liquefied natural gas) were 42.5 billion cubic meters, an increase of 31.1%; apparent consumption was 147.1 billion cubic meters, an increase of 11.1%.
